Intel's octacore server chip, the Xeon 7500 Nehalem-EX, is built on the 45nm process. For the next big evolution of the Xeon line, Intel hopes to be pushing even more cores when it takes it flagship to the 32nm Westmere-EX generation.

While the Westmere 32nm technology is in the Xeon 5600, Intel plans to extend that technology to EX sometime next year. Stephen Smith, vice president and director of PC client operations and enabling at Intel, said during a webcast speech that the upcoming Westmere-EX chips will be targeted at systems with four sockets or more. The good news is that the Westmere-EX chips will be socket compatible for those who have already invested in the latest Xeon servers.
